BRIEF SUMMARY OF THE INVENTION
Primary features of this new variety which connote a distinctive advance over existing types are the gross abundant and continual blooming taken with the perfection of the fully double flowers of an old-fashioned, more particularly apparent inthe accompanying illustration of a specimen thereof.
BRIEF DESCRIPTION OF THE DRAWING
The drawing is a colour photographic representation of a new variety of flush of bloom taken substantially in side view and showing inflorescence in various stages, stems and foliage of the plant.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description of the new variety, colour terminology being in accordance with the "Methuen Handbook of Colour" published by Eyre Methuen Ltd (1963).
Variety denomination (in accordance with the UPOV Convention): Auswhite (Trade name The Swan).
